Being an insurrectionist requires an actual ability to perform an insurrection, which is why all the charges have been trespass, assault, and interfering with government workers/property.
Unlike the CHAZ/CHOP people who actually took over portions of a city FOR MONTHS, and haven't been charged for an ACTUAL insurrection.
Being an insurrectionist requires none of that, only the intent and acting on that intent. Because they were incompetent doesnt make it any less an insurrection.
The LEGAL BAR for charging some one with insurrection is pretty high, and very rarely done because our government prioritizes free speech rights and this applies to a lot of the reluctance to come down hard on protests. That is one they are charging them with other crimes instead. The other aspect is that it was not one coordinated action. There undeniably were those who coordinayed and planned an attempted violent overthrow of our electoral process and utilized a fired up mob towards that end. However there were many who were just stupid and caught up in it. Not everyone will be charged the same nor should be.
